- 癌症预后 癌症预后
背景情况:
- 非小细胞肺癌 (NSCLC) 经常发展为大脑转移 (BM),导致患者预后不佳.
- 表皮生长因子受体 (EGFR) 突变在NSCLC中很常见,影响治疗反应和存活率.
研究的目的:
- 为了评估脑转移 (BM) 在患有EGFR突变的NSCLC患者的预后影响.
- 为了确定独立的预后因素,并开发一个预测模型的生存在这个患者队列.
主要方法:
- 对692名患有EGFR突变的晚期NSCLC患者进行了回顾性分析,这些患者接受了氨酸激酶抑制剂 (TKI) 治疗.

01:21Cancer Survival Analysis
311
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
